RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 721,524, dated February 24, 1903. Application filed May 17,1902. Serial a. 107,787. (No model.)

To all whom it natty concern. w Be it known that I, FRANK S. PASCOE, a citizen of the United 'States,residin g atAll'egheny,

inthe county of Allegheny and State of Pennsylvania, have made'certain new and useful Improvements in Rail-Joints, of which the following is a specification. a 7

My invention is an improvement inrailjoints, and has for an object to provide asimple novel construction whereby the joint may be securely locked when applied and thelocking key or section will be retained in position by the lockin g device; .and the invention con-. sists in certain novel constructions and combinations of parts, as'will be hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of the joint as in use. Fig. 2 is a detail top plan view of the main section of the chair. Fig. 3. is a bottom plan view of the locking key or section. ing-vblockin detail. Fig. 5-is across-sectional view on about line 5 5 of- Fig. 1; and Fig. 6 is a detail section on about line 6 6 of Fig. 5, the locking-block being omitted.

My improved joint includes a chair'A, the

locking-key B, and the locking-block C, by

which the key is locked in the main chairi ecticin A when applied thereto, as shown in The chair A has a base A, which may be sloped on its under side, as shown in Fig. 5, so as to let one end of the cross-tie low enough to receive the casting underv the rail and allow the other end of the .tie tocome up tight against the rail, as will be understood from Fig. 5. At one side the chair A has the integral upright fish-plate aand is provided at its opposite side with an upturnedwing'D,

which is grooved or recessed in its inner side at D and is undercut on its inner side at D to receive the locking-keyB and is also sloped Fig. 4 illustrates the look I B. The base A of thechairis also provided with a shoulder ct'opposite the side of the chair having the fixed fish-platesection and completing the seat for the base of the rail, the shoulder a lying below the base'of the socket E, which opens inwardly, as shown in Fig. 5.

nal taper of the upright D of the chair and the undercut inner edge of said wing, as will be understoodfrom-Figs. l and 5. This locking-key Bis provided with an outwardly-opening socket F, which in the locked position of the parts coincides withthe socket E in the chair and receives the locking-block'O and the spring G for actuating said block outwardly into the socket E, as shown in'Fig. 5, in which adjustment of the parts theblock O fits partly in both sockets E and F and tends ,to lock 'the locking-key from displacement. The locking-key is also provided in its under side with a groove H, extending from its point end nearly to the socket F and which fits and slides over the spikes I, which are driven throughthe spike-holes a in the base A of the chair and restin notches J in the base of the rails J. The locking-key thus operates to retain the spikes I, and yet can be slipped longitudinally in' the chair along the heads of said spikes to the locked position, as shown in Fig. 1. The locking-block O is sloped on its outer face at C to conformto the longitudinal and vertical slope of the inner edge of the upright wing D of'the chair, so the said block when pushed in and started against the inner face of the said portion D can move along said face with the locking-key until it registers with the socket E, when the spring G Williorce the, said blockC to the locking position. (Shown in Fig. 5.)

-In the operation of my invention the rails J fit in the chair and are secured by the spikes *I, fitting in the notches J in the bases and passing through the holes A in the base of the chair. The locking-key is then adjusted with its point end at the wide end of the seat for said key provided in the chair, and the block 0 is pushed back in its socket F until the outer edge of said block moves against the inner face of the upright portion of the chair, when the locking-key B can be pushed longitudinally to the locked position, (shown in Fig. 1,) in which position the block 0 will project into the'socket E and lock the key from displacement. In thus sliding the locking-key to locked position the groove H receives the heads of the spikes I. In order to release the block 0 and permit the withdrawal of the locking-key whenever desired, an aperture K may be provided, leading from the outer end of the socket E outwardly through the upright portion D of the chair A in position to receive a pin by which the block 0 may be pushed back out of the socket E to permit the withdrawal of the key.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of the rails provided with the base-notches J, the chair having the fish-plate section at one side and provided at the opposite side with the base-shoulder a, and above and beyond the same with the upright portion D having its inner face sloped longitudinally and undercut vertically, and provided in said face with the inwardly-opening socketfor the locking-block and with the pin-hole K leading to the outer end of said socket, and the locking-key having the upright fish-plate wing and having its base portion grooved longitudinally at H and provided with a socket F for the locking-block and the said block and its actuating-spring, all substantially as and for the purposes set forth.

2. The combination of the chair having an upturned portion and provided in the inner face of said portion with a socket opening at its inner end below the upper surface of such upturned portion to receive the lockingblock, the locking-key provided in its outer face with a socket for the locking-block, and the locking-block and spring, substantially as set forth.

3. The combination with the chair provided at one side with the upturned portion having its inner face sloped longitudinally and undercut vertically, the locking-key, having its outer face coinciding with that of the upturned portion of the chair, sockets being provided in the abutting faces of said lockingkey and upturned chair portion, and the locking-block arranged for operation in said sockets, whereby to lock the key from longitudinal movement, substantially as set forth.

at. The combination of the chair having the upwardly-projecting portion at one side, undercut and sloped at its inner face and provided with a socket leading from said face, the locking-key having in its outer edge a socket which may be moved into register with that of the upwardly-projecting portion, and the locking-block and its spring, substantially as set forth.

5. The combination with the chair having a, socket for the locking-block, of the lockingkey sloped longitudinally at its outer edge and provided with a socket leading from said edge, the locking-block having its outer end sloped,aud the spring foractuating said block, substantially as set forth.
